To all whom z'tfmay concern Be it known that I, ALBERT D. GROVER, acitizen of the United States, and a resident of New York city, New York,have invented certain new and useful Improvements in Vending-Machines,of which the following is a specification.

. My invention relates to vending machines and has for its object ingeneral the provision of a machine particularly adapted for use inlocations where space is very limitedas for instance in street cars orrailway cars, where it can be readily attached to the wall or postsbetween the windows. In other words, the machine of my invention isdesigned to take up as little room as possible and will not projectsuiiiciently from its support to be considered an obstruction. In amachine which I have actually constructed in accordance with theinvention herein disclosed, the depth of the machine casing was aboutthree fourthsV of an inch, and the width about two and one half inches.The height of course will depend upon the number of packages (such aschewing gum, candy and the like) which the magazine shall contain. v

In order to reduce the depth of the machine to a minimum, I provide amagazine adapted to contain the vendible articles edge upon edge in avertical column which rests upon an adjustable supporting mechanismoperable to releasethe articles one by one. In the broad aspect of myinvention, this supporting mechanism has upper and lower supportingportions movable with respect to each other, so vthat before one portioncan pass fully into releasing position, the other portion reaches asupporting position. lThis absolutely insures the release of thearticles one by one.y With this supporting mechanism, no separateejecting device is necessary, which adds greatly to the coinpactness ofthe machine.

More specifically considered, my new form of supporting and releasingmechanism comprises two pairs of oppositely arranged levers at the lowerend of the magazine. Normally, thecolumn of articles rests upon the twolower levers. rEhese are so connected with the upper levers that beforethe lower levers mcve out of support-ing position, the

upper levers engagethe column of articles above the iowermost articleand support the entire column as long as the lower levers' are inreleasing position. Not until the lowery lslide which is verticallyVmovable and operated from the outside of the machine by any suitablemeans-such as a knob or wheel. rIhisslide is normally locked againstVfull movement, but is unlocked through the medium of the depositedcoin. When the last package has been discharged from the magazine, theslide is automatically locked in its lowermost position to prevent theinsertion of a coin into the machine. The above and other objectsV andadvantages of my invention will become apparent from a detaileddescription of the drawings which show a machine embodying the variousfeatures of my invention in a form now best known to me. In thesedrawings, Figure l, is a front view of the machine, with the front wallof thecasing broken away in order to expose the interior mechanism toview.; Y f

Y Fig. 2, is a longitudinal section on line 2 2 of Fig. l. j

Fig. 3, shows a viewy similar to Fig.' 1,

with the coin slide and the supporting mechanism in operated position.Fig. 4, shows a horizontal section sub stantially on line 4-4 of Fig. l.v

Fig. 5, is avertical detailed section on lineof Fig. 3, showing the coinslide in locked position when the magazine is empty and 'Fig 6 isa'vertical detailed section 'of aV formed kof twosections-a rear sectioncomprising a rplate land a front section comprisingthe front wall 2,sides 3 Vand 4, top 5 and bottom 6. The twosectionsare secured togetherin any convenient way. In the drawings I have shownthe back plate 1Vprovided with side iianges 7- for receiving the sides 3and24, as shownFig.' 4, `,and

with a bottom flange 8 which provides a recess 9 for receiving theflange .10 on Vthe bottom plate 6. The front section of the casing isheld locked against the back plate s Vmachine is adapted to be securedin place on any desired supportcarri es the lmagazine containing thevendible articles. This inagazine may be conveniently formed of a pairof sheet metal bars 15, having rear flanges 16 for receiving suitablefastening devices, and

front flanges 17 for retaining the packages within the magazine. As seenfrom Figs. 2 andA 1, the depth of the magazine is very slight, so astoretain the articles or packages P` edge upon edge in a verticalcolumn. These packages P may contain any suitable CQIlfeotions-such aschewing gum or candy. The heightk of the machine would vary inaccordance with the capacity of the magazine. I yhave provideda novelmechanism for supporting the packages in the'magazi'ne and releasingthem one `by one, without danger ofmore than one package being releasedat each operation ofthe machine. Broadly speaking, this mechanism hastwo separate and distinctive engaging portions, one for supportingpackages when the mechanism is in normal position, and the other forsupporting the packages when the mechanism is 1n operated position.These eiigaging portions are movable relatively to each other, so thatone portion passes into engagying position before the other portionreaches a releasingpositio'n. In this way the'col'- umn of packages isnever without a positive support. Referring now in detail to the speific form vof supporting and`V releasing mechanism shown iii thejdrawings, it will be seenthat I have provided a pair` of lower levers18v and a pair of upper levers 19. lEach VLpair of levers 18 and 19 ispivotally mounted on a pin ory stud 20 carried by the .back plate 1. Thetwor pairs Vof levers are mounted upon oppositesides of the packagemagazine atY the lower end thereof,

and are so arranged that when the levers 18 are in norma-l position, thelowermost pack- Y age P rests at its ends directly upon the supysoporting lugs 21 which'V .f project inwardly' from' the levers-18. Theselevers areheld in 4normal, position by spring blades 22 secured kto thesides of the casing at23 and Vadapted attheirvfree ends tobear ragainstthe pins A24e projecting laterally Afrom the :levers 18.

Any. Y other .suitable arrangement may of coursebe providedfor-holdingthe levers 18 in normal position. Th'eup'per levers 19 areyieldably connected with their vrespeck tive ,llwer levers 18 by means`of springs 25.

The upper end of each 'of these springs is ccnnected toV the upper leverI 1-9 and the lower end to the lower lever 18, while the intermediateportion of the spring is coiled about the pivoted stud 20. Theconnection Vof the springs 25 is to hold the levers eX- in the slots 27formed in the upper levers 1.9.

At their free ends, the levers 19 are' provided with pointed projections28. The connection between the levers18 and 19 is such that when thelevers 18 are in supporting position, the pointed projections 28 on thelevers 19 are out of the magazine. However, when the levers 18 are movedoutwardly (by means to be presently described) into releasing position,the levers 19 are rocked inwardly and the pointed projections 28 enterthe magazine and pierce the sides of the package above the lowermost onesuiiiciently to support that package and all the packages above it. Fig.3 clearly shows the levers 18 and 19 in operated position. The movementofthe levers 18 and 19 with respect to each other is so timed, thatbefore the supporting lugs 21 of the levers 18 have moved out of contactwith the lowermost package, the pointed projections 28 on the levers 19have iirmly engaged the package above the lowermost one, and thussupport the entire column while the released package falls ontA of themagazine, through the delivery-chute 29 into the pocket ordeliveryopening 30. In Figs. 1 and 2, the delivered package is shown atP1. To enable the package to be readily grasped by the patron, the frontwall of the casing is cut away at 3l and 32. It will be noticed that thepackages are delivered end-on. The chute 29 and the delivery-pocket 30are formed by a partition 33 suitably secured to the front section ofthe casing. Vhen the springs 22 return the levers 19 to normal position,the levers 18 remain in operated or retaining position until the pins 26strike the outer ends of the slots 27.Y Vhen this occurs, however, thelugs 21 of the lower levers 18 havey already moved into supportingposition, so that when the continued movement of tlielevers 18 rocks thelevers 19 out of retaining position, the released column of packagesdrops on to the lugs 21. By this `means it is impossible for more thanone my new form of supporting and releasing mechanism, the relativemovement of the levers 18 and 19 always insures the'movement of theupper levers 19 into supporting position before the lower levers 18reach a releasing position, and vice versa. Broadly speaking, theleversj18, either or both of them, may be properly considered as asupport or supporting device which normally supports the column ofarticles within the magazine, while the levers 19, either or both, maybe considered as yieldable means controlled by the levers 18 to sustainthe column of articles in the magazine when the support is moved oradjusted into releasing position.

The levers 18 are moved outwardly into releasing position by means ofthe coin slide 34 which is mounted in the front section of the easingfor vertical'reciprocation The lower corners of the coin-slide 34 arebeveled, as shown at 35. The slide 34 with its beveled or cam portions35 may as a whole be considered as a cam device which operates thesupports 18 and 19. From the lugs 21 on the levers 18 project forwardlythe extensions 36 which are arranged to be engaged by the beveledportions 35 of the coin-slide as the latter is moved downwardly. In thisway the levers 18 are rocked outwardly from supporting into releasingposition upon a complete downward movement of the coin-slide 34. Thisslide is guided in its movement by the plate 37 suitably secured to thefront wall of vthe casing.

Complete downward movement of thecoinslide 34 is normally prevented bythe pins 38 carried at the upper ends of the two levers 39 which arepivoted on pins 40 secured to the guide plate 37. The pins 38 are attheir outer ends semi-cylindrical, as clearly shown in Fig. l, andproject into the slots 41 formed in the' coin-slide 34 on opposite sidesof the projection 42. The

. coin-slide is also provided with a downwardly extending projection 43having a curved recess 44 which coperates with the curved end 45 of theprojection 42 to form the opening 46 for receiving the deposited coin.On either side of the recess .44, are provided stop shoulders 47 whichare arranged toencounter the pins 38 as the slide is pushed down. Thelevers 39 are held inwardly by the springs 48 secured at their upper.ends-to lugs 49 vmounted on the .front section of the casing. Stops 50are arranged to limit the inward movement of the levers 39. .Thenormally free movement of the coin-slide 34 is insufficient kto bringthe beveled corners 35 into engagement with the extensions 36 on theYlevers 18. However, when a proper coin is deposited in thecoinlreceiving opening 45, and the coin-,slide is thereupon operateddownwardly (through connections to be presently described), the

coin engages the pins 38 and forces them outwardly into verticalalinement with the 'slots 51 formed at either side of the provjection43. W'ith the pins 38 in this posicoin-slide to have full ejectingmovement.

As already described, when the coin-slide is moved downwardly to itsfullest extent, the

beveled corners 35 engage the extensions 36 of the goods-supportinglevers 18 and force the same apart outwardly to release the lowermostpackage which falls into the pocket 30 through the chute 29.- The Jfrontplate 2 of the machine casing is provided with a coin-entrance opening52 which registers with the coin-receiving opening 46 on the coin-slide34 when the latter is in normal position.

It should be noted that the coin-engaging pins 38 also serve as acoin-testing device. For instance, if the deposited coin is ofinsuiicient diameter, the pins 38 will not be forced outwardly asuiicient amount to clear the shoulders 47. Should the deposit-ed ycheckbe of soft or yieldable material, such as lead, paper and the'li'ke,'theedges ofthe semi-cylindrical pins 38 will bite into the material or' thecheck and thereby act as a positive stop against the further downwardmovement of the coin-slide.

Preferably, the opening 52 is surrounded by an inwardly extending fiange53 which cooperates with the fixed plate 37 to guide the coin-slide 34in its movement.

The coin-slide 34 has rigidly attached thereto a rack 54 arranged tomesh with the pinion 55- fixed to the inner end of the stub shaft 56.This shaft projects to the outside of the machine through an opening inthe front panel 2 and is at its outer end provided with Va suitablehand-operated membersuch as a wheel-or knob 5,7. It is evident that whenthe knob 57 is rotated in a clockwise direction, the coin-slide`34 ismoved downwardly through the rackand pinion connectionfjust described.Fig. y'1 shows the coin slide in upper or normal posi'- tion,while Fig.3 shows the same inilowermost or operated position. The coin-slide isreturned to normal position lby suitable spring means-such as acontractile spring 58 which is secured to the coineslide vat 59 and tothe casing at 60. A

yOn top of the column of goods in the magazine rests a weight'61provided with a pair of beveled projections 62, as best shown in Fig. 4.Really only one projection would Y 37 is at its lower end provided witha recess 63 from lwhich extends yupwardly the slot 64. This slot andrecess serve to accommodate the dog 65 which is pivoted on the pin 66carried by the 'guide plate 37 at the recess 63. kA spring 67 coiledabout the pin or stud 66, engages at its upper end the pin 66 carried'by the dog'65 and at its lower end bears against the guide plate 37 tohold the dog 65 normallyin backward position, as shown inFig. 2. At itsfree end, the dog 65 is provided` with a projection 69 having anupwardly extending point 70. This point is adapted to engage the beveledupper end 71 of the slot 64 to limit the rearward movement of the .dog65 under the influence of the spring 67. When the last piece of goodsdrops out of the magazine, one of the projections 62 on the weight 61comes in contact with thedog 65 and forces the same forwardly into thepositionshown in Fig. 5. Itshould be understood thatl this forwardmovement ofthe dog 65 takes place to inform the patron ofV that fact.

when the coin-slide 34 is in lowermost position, so that the nose orprojection 69 of the dog engages the shoulder 72 on the coinslide. Thispositively locks the coin-slide in lower-most position, and prevents thedeposition of fl'lrther coins into the machine. Preferably,thecoin-slide carries a suitable sign or mark such asfthe word Emptywhich registerswith thecoin-,opening 52 cf the front plate whentheimachine is empty,

To unlock the coin-slide, lit Vis/necessary to remove the front sectionof the machine and restore the dog 65 to normal position by hand,whereupon the coin-slide is drawn upwardly Ainto normal position by thespring 58.

After the magazine has been filled with the vdesired goods, the weight6l is placed on top of the packages, and the front section of the casinglocked in place again, whereupon the machine is ready for operation asbefore. kThe weight 61 is at its sides provided with grooves 73toaccommodate the points 28 .of the levers 19.

In orderto preventthe machine from being operated kby washers, kIprovide a pawl 74 pivotedat 75 tothe guide plate 37 and provided atitslower end with a forwardly projecting hook 76 arranged to extend throughthe openingv 77 in the guide plate.

- A leaf spring 78, Xed to theguide plate 37 at the points 7 9, bears atits lower end against the shoulder 8O formed at the upper end of thepawl74, to force lthehook 76 forwardly@ The .pawl 474 ispivotedxsubstantially midway vof the guide plate 37, as best shown inFig, 4, and is readily accommo- .dated in the space between the guideplate andk themagazine. p When' a washeris deposited in thecoin-receivingopening 46 and the knob '57 .rotated tomove the coin-slide34 downwardly, the' hook 76 of the pawl 74 enters the opening in thewasher before the slide is moved downwardly any great extent, andthereby positively locks the slide against further downward movement.Fig. 6, shows how the hook 76 of the pawl 74 has entered the opening inthe washer 81. Ihen the knob 57 is released, the coin-slide 34 iscarried back to its normal position, together with the deposited washer.This movement is permitted by reason of the fact that the hook 76 isbeveled at the bottom, so that it is cammed rearwardly by the washerduring the return movement of the coin-slide. The washer is thereforecarried back to the coinopening where it can be removed.

The pawl 74 serves another purpose, and

lthat is to eject the coin from the coin-slide forced out of thecoin-slot 46 by'the hook 7 6A and drops into the cash box 83. Thisejection of the coin by the pawl 7 4 does not take place until after thepins 38 have entered the slots 51 in the coin-slide 34.

' The operation of my new machine will be clearly understood from theforegoing detailed description, and it is not therefore believednecessary to repeat the same. Although I have described one specificform of machine embodying the various features of my invention, I wouldhave it understood that I d0 not intend to be limited to the details ofconstruction set forth, as it is obvious that various changes andmodifications may be made without departing from the scope of theinvention as defined in the appended claims.
